After-gate attack on a quantum cryptosystem
Wiechers, Carlos; Lydersen, Lars Vincent Van de Wiel; Wittmann, Christoffer; Elser, Dominique; Skaar, Johannes; Marquardt, Christoph; Makarov, Vadim; Leuchs, Gerd (Journal article; Peer reviewed, 2011)We present a method to control the detection events in quantum key distribution systems that use gated single-photon detectors. We employ bright pulses as faked states, timed to arrive at the avalanche photodiodes outside ... -
Controlling a superconducting nanowire single-photon detector using tailored bright illumination
Lydersen, Lars Vincent Van de Wiel; Akhlaghi, Mohsen K.; Majedi, A. Hamed; Skaar, Johannes; Makarov, Vadim (Journal article; Peer reviewed, 2011)We experimentally demonstrate that a superconducting nanowire single-photon detector is deterministically controllable by bright illumination. We found that bright light can temporarily make a large fraction of the nanowire ... -
Controlling an actively-quenched single photon detector with bright light
Sauge, Sebastien; Lydersen, Lars Vincent Van de Wiel; Anisimov, Andrey; Skaar, Johannes; Makarov, Vadim (Journal article; Peer reviewed, 2011)We control using bright light an actively-quenched avalanche single-photon detector. Actively-quenched detectors are commonly used for quantum key distribution (QKD) in the visible and near-infrared range. This study shows ...
